I Have done the attachment electronic circuit as shown in the figure.
I would like to know how to do the analysis of the electronic circuit to
chek the the filter frequencies.
The filter frequency in common mode and the
differential mode, and I also would like to know
how to make a simulation to check the specifications
of the design frequencies. (Common mode and diferential mode)
The design frequancies of the filter were the fallowing:
diferential mode: 25 Hz and common mode 3 kHz.
That specifications were made according to the Datasheet.
Any answer is going to be very welcome, and thankyou for
Actually I´m thinking in make a superposition analisys or look
like a separate inputs for each input like a individual LPF for
the diferential mode, but I still have doubts with that and
the way to test in the simulation.
I am working in Proteus but I also have Multisim.
The power supply is for -12 and +12 volts with a Gain
of 750 and an input of 6.67 mV to achieve the maximum
value of 5 volts.
The application was for a load cell in a Weighing scale and
it worked very good, only I Have those questions to improve
a little more my justification and not only the equations or other calculus.
